>I also just keep long running notes for tracking things workouts and meals with headers for dates.

This I'd say fine on the phone but frustrating heading to the Mac and start wishing for at least a spreadsheet.

What exactly makes you wish that? I used to use google sheets for workouts but realised:

1. plain text notes are more ergonomic on the phone

2. dumping them into Claude produces more useful analysis than I could hope to extract for the same amount of effort.
